Assembly Integration & Test Engineer, Satellites

Vast is developing next-generation space stations and space infrastructure using an incremental, hardware-rich, and low-cost approach. Vast is rapidly developing its multi-module Haven Station to ensure a continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and unlocking a new space economy for government, corporate, and private customers. Haven Demo’s 2025 success made Vast the only operational commercial space station company to fly and operate its own spacecraft. Next, Haven-1 is expected to become the world’s first commercial space station when it launches in 2027, followed by additional Haven modules. Additionally, the company recently announced Vast Satellite , a high-power satellite product line leveraging its space station components and the heritage of Haven Demo. Headquartered in Long Beach, California , and with more than 1,000 employees and over a billion dollars in private capital, Vast has built the facilities required to manufacture and operate America’s next space station. The company plans to develop future habitats and systems for the Moon and Mars, dedicated space stations for government partners, and other crewed systems that will unlock the expanding long-term space economy. This is the founding Assembly, Integration & Test Engineer position for the satellites vertical. The team has two openings available at L2, Senior, or Staff level. You will not be inheriting a factory, a set of procedures, or a test stand — you will be building them. You own how a Vast satellite gets physically built, integrated, and proven flightworthy, from the first development unit through a production line that has to turn out flight hardware at rate. You will write the integration flow and the test philosophy, stand up the environmental test capability and the ground support equipment, lead the campaigns that use them, and then feed what you learn back into the design so the next ten units build faster than the last. You'll do this working directly alongside the discipline leads for structures, avionics, thermal, power, GNC, and flight software. If you want to define how spacecraft get built at a company rather than execute someone else's definition of it, this is that job. This will be a full-time , exempt position located in our Long Beach location. Responsibilities: Integration & Test Lead and own integration and test campaigns at every level of spacecraft development — component, box, subsystem, and full vehicle Define the test philosophy for the bus: what gets acceptance tested, what gets protoqualified, what qualifies by similarity, and how that philosophy holds up as we move from a one-off development unit to rate production Develop acceptance, qualification, and R&D test plans for spacecraft systems, and drive them through execution and closure Work with systems and subsystems leads to defining requirements and the verification and validation plans…
